Compering maps

Today, I read a news which was about a service for map.

Recently, we use google, yahoo  or other maps on your computer and your mobile phone. I like there system, because I don't need to being any paper when I go some unknown places (in my country.) And, we can make virtual travel using the map.

The following link is point to a service for a map which you can compare current map in Japan and old days map in Japan at same screen. The current version has limitation for supported area, however you can check for big cities as Tokyo area, Osaka area and some others. (And the service is provided in Japanese. I don't think you don't need to be able to read japanese when you check the map in many situation. )

When you want to find new your house, you can check the old days' structure of ground. There are many earth quake in japan. So, if your new place were in a sea or river, then you will have many risks for living in your new house. In such situation, we can also use this service.

If you like to read novels about history, then you can role back to 100s years ago.

Password.....Password?

I'm not specialist for security and I don't know very well about google authentication mechanism.

However, recently, many web sites use google authentication mechanism. It is good idea because the site administrator does not need to have clients' passwords. And, I also like using the services onto many web sites. It is for not only security but also easy to make new accounts.

However, some sites are support not only for desktop/ laptop service but also mobile clients. Yes, I also want to use there services from my mobile phone. However, in many cases, I need to input my login name and login password onto the mobile clients. Well..... I thought I don't need to input any password when I want to use there services, because I use google account. And, I don't have any password on the server, because I didn't create any password....

I think the mechanism is worth than not to use google account. Because some people who has no interest in computer use same passwords on many web site. If the site will get attack by malicious person, then he will lose not only the site account and data but also google login account. (Lose or have problem....) It is double attacked~_~;;;;;

And when I want to make password onto the site, there is so complex to find the place where I can set up my new password.... And..... I can not remember there passwords.......ToT


Well.....This blog got 30M people of access at last weekend since I made this blog. I was so surprised. Because I just started to write this blog for my hobby and for using english. Thank you so much for coming this blog.

security policy <--> system design <--> contents design

Last week end, I went to Tokyo for recruit activity.

After finishing everything, I met with my friend's couple. We enjoyed the time. And we went to showroom for a thing (I should not say more ^^;;;), because we had small time. Then the organization provides a terminal which introduce about their activities. I found security hall in the system, which comes from weak communication when they design the system. The system is following.

The system has only one input device, which is mouse. The system provides full screen web browser. The web browser is limited version for function.  The system has no keyboard. So, users can use only the limited web browser. And the organization uses twitter. The twitter account publishes about their activity with no link or link to inside of there contents. This meaning is that users can not exit from their contents. (usually....) If the system provides only above, then this system is completely perfect. However, the twitter's account profile links to another web site in their organization. And the page links to their facebook account. This is problem. Usually, if user publish something onto facebook and some other user push like button, then all users can go his/her personal timeline on facebook from a list what provide a users who push like button. Even if the organization did not publish any links to other site, however the system user can go out to 3rd parties' page. If the time line has malicious link then the site will have problems.

This problem comes from communication miss. (I think.) There is 4 pages. Homepage on the system, twitter, other official page, and facebook. The system designer considered about only homepage showing. Accidentally, the homepage designer needed to link to their twitter account. And, the twitter account manager was different team from the system manager team. And (maybe) the twitter manager did not know the twitter is linked from such limited system. Then the team linked other official page. Sure, the page manager clearly don't know first homepage. The team linked both of twitter and facebook account for promoting. If at least one engineer or manager knew every services then the error was not occurred.....

When I saw the site, I really felt scared. The system itself, the organization considered about security. However, the contents management can easy break the security policy, if they don't have security concern.......

(maybe) I will write mail to them about this problem.......If I have time and stamina  ^^;;;;;

How to install stencil to OmniGraffle, when the installing is not work correctly.

Yesterday, I fought with installation of OmniGraffle Stencils.
OmniGraffle is designing tool for diagrams, website elements, and graphics. This tool is strong for them on MacOSX.
http://www.omnigroup.com/products/omnigraffle/

Stencils are set of clip arts for omnigraffle. In default, OmniGraffle has enough stencils, but you can DL from following site, too. I wanted to use some specific clip arts, so I try to find them from following site.
http://graffletopia.com/

When I downloaded UML2 collection from the site, the package was wrapped with ZIP. So, I unziped it. Then the file has no extension. Usually, we just need to double click the downloaded file for installing the stencils. When I double clicked the file, Mac OSX detect the file to open with XML editer. I tried something for installing it. But it was not working include manual installing.

Today, I downloaded other stencil form the site. Then the file has an extension as "gstencil". And, I could install the stencil with double click.  Finally, I tried to add extension as "gstencil" for UML2 collection file, then OSX detected correctly.

How to use several virtual desktop on osx (linon)?

Usually, I used two or more virtual desktop on mac osx (before snowleopard). Commonly, we can use virtual desktop using "control and right or left arrow button."
However, after the lion, i could not find any virtual desktop. Today, I find this virtual desktop function on lion. On default, there is only one virtual desktop. When you press F3 button, you will be able to see all windows at same time. On this screen, you will see + button top and left side of the screen, when you move mouse cursor to the point. Then click the button. You will be able to use several other virtual desktop.

For the removing the optional virtual desktops, you just need to push x button on the list of virtual desktop on the top of screen.

Box.com for osx : official client comes


   There are many cloud strage services in the world. For example, Dropbox, suger sync, google drive and box.com.

   Today, I focus to box.com. Because, lately, box.com started to provide a new version of client for Mac OSX. The previous version's client of box.com for OSX had many limitation. The largest problem was that the client can not sync between local strage and box.com. The previous version could just mount as ftp servers and add or remove from the system. It was big limitation for using cloud stile of strage.

  However, the strongest part of box.com is strage size. Now, I can use 50GB for free. So, I didn't want to remove this account. On another side, it was difficult to manage data on Mac OSX. Because I needed to access from web browser to box.com then to upload file from the interface on web browser.

  Now, the lastest version of client for box.com starts the sync function on OSX. So, I try to use new version.

  My stile for cloud strage is following. I use cloud strage for my work and private. For the working use, I use dropbox. Because many of my known people are using dropbox. So, dropbox is very easy way to share the documents with other workers, when we collaborate with others. And, dropbox can keep histories for each file for versioning. This meaning is when we get some problems on local, however we can rollback to previous version, when the documents were stable.  For the private use, I use suger sync. Because, there are few users around me. So, I cannot share the documents with other workers. However, suger sync is also good cloud strage as dropbox. So, I use suger sync for my personal uses.

  Now, my suspecting was the cloud strage is safe or not. Because even if the cloud strage makes backup many times, however the no system is perfect. Sometime, the system has bug, or the system has fuman error. Recently, some of cloud strage service was crashed because of human error. Then all of data was unrescuable  states. Luckily, I didn't use the service. But it is not only thing.

  So, I want to backup's back up to other site. Dropbox and suger sync are provides less than 20GB for free. And box.com provides 50GB strage for free. It is possible to make full copy on box.com. Because of above reason, I try to use box.com client for Mac OSX.

  Installation is very clear. I was not confused any point. When I put some file on the synchronized directory, the client started to synchronizing automatically. The synchronizing speed is almost same as dropbox ( I didn't evaluate anything. Just my experience)

  Weak points of this client is following.
I cannot move any files or directory inside the synchronized directory. If oyou want to move files or directories what are inside the synchronized directory, you need unsync from web browser at once. Then I can move there files or directories. After moving there, I can set active for the sync function. So, first design of directory structure is little bit difficult. But, after making such structures, It will be OK( I think, now.) From the above reason, after moving files, the client remove all files at once then redownload them again to correct directory. If your computer has HDD then it is ok, however if your computer has only SSD then I was worried about this.... Writing time is so big.

  I try to continue to use this client, then I will re-review of this client after I'll use very well.

Bicycle insurance in japan

Long time, I was considering about bicycle insurance.

Many japanese are not consider about insurance for bicycle in japan. Because japan is weak country for insurance.

Many people considered about when they are attacked by car. They didn't have an idea what they may be going to be individual at fault. However, road bikes are faster than my MTB. And, many of city bikes do not turn on a head light after sunset. The old person has also no idea what the bicycles can ride so fast as 50cc motar bike. Then they easy enter in front of bicycles. Such kind of accident is not few in japan. And, the worst case of such accident, the road bike rider needed to pay 40 millions yen to attacked person.

Bicycle ride's bad manner have begun to social issues. Some bicycle riders do not follow the traffic lights or traffic signs. In such background, sometime, I have risks what I will be attacked by such bicycle riders when I ride my MTB. However, as above reason, many riders have no insurance for riding sports bike or city bikes. In such case, I will need to use my insurance.

Because of above things, I was finding an insurance for bicycle. Then I asked about this insurance to the owner of bicycle shop. He said there was insurance for bicycles before 2005. However, the insurance was finished by some reasons. The largest reason is that the price needs to low. Because many customers were injured person or had small accidents. However, total number of accidents were not small. And another reason is the law of insurance. Before 2005, the bicycle shop owners could sell an insurances to there customers. However, now, they need some licenses for insurance selling. Then many of bicycle shop owners could not sell. By such reasons, bicycle insurance was removed by insurance corporations.

So, how can i get it?
Now, we have three choice.
1. If you have private insurance for car driving, then you can add the option for riding bicycles. This support space is not only for you but also your families. Many corporations need another price for this option. However, Nihon-koua-sonp (name of insurance corporation) do not change the price for this option. Luckily, I have been this insurance before I knew. If you have a car, then this is the most reasonable way to have insurance for bicycle.

2. Some insurance corporation provides an insurance for bicycle riding. However, the price of this insurance is not cheep for bicycle insurance. (the owner said)

3.Last way is maintenance insurance by the organization of bicycle. This insurance is only way what you can get it from bicycle shop. This insurance is for good maintained bicycle. This good point is you can get not only insurance but also maintained your bicycle by shop. The price is 8000 jpy (I'm not sure, I forget exact price. ) However, the insurance has a upper bound of limitation for the payment. And same as car insurance by law, the payment is for the opposite side (injured person.) However, at least you can pay for it.

The owner said that the government makes infrastructure on the road for bicycle for separating from walker or car driver (dependent of the traffic condition). However, they don't focus to the insurance even if the traffic accident is not small numbers. Same as 50cc motar bike, bicycle environment should also have an insurance by law at least for injured person. However, for that, the low should obligate the helmet wearing. This two thing will kill the freeness of bicycle. So, it is difficult choice. I agree ^^

PET bottle tea

There are many kind of tea in the world. Japanese also drink many kind of teas. Maccya is one of the famous japanese tea. Usually, many kind of teas are filtered for preparing. Maccya is used tea leaves powder. So, we can drink tea leaves themselves, too.

Well, as a title of this post, there are many kind of tea what is bottles into PET bottles. We can easy to find them in convenience stores. Usually, the pet bottle tea is already filtered.  The filtered tea bottles are also tasty. But I like following product's both of taste and idea.

The bottle has capsule inside the cap. Can you see the cap of this bottle? This cap is much longer than usual PET bottle. And inside of the cap has a tea leaves powder as next picture. And, the body has just water. It is usual water until we open the bottle cap.















This picture is about cut plane of cap.
The dark green part is hard cap. And white part is mouth of bottle. Light green part is the powder.

Next picture is about the real documents how to open and drink this tea.





This is overview and next three pictures are detail of parts of the picture.













 1. Open the cap of this bottle. Then the capsule can be separated from the cap.





2.Then the capsule follow down into water.












3. You just need good shaking the bottle until the powder inside a cap will be melted in water.












If you have interest in drinking tea then you also know the relation between taste of tea and the time from prepare. The taste will be decreased time by time. So, just after to be prepared tea is much better than the tea what is prepared 10 hours ago. Like as above, we can drink the tea what is prepared just before to drink.

I like this idea ^^

Photo : Android, Dropbox, Google+

Almost all of week end, I ride my MTB in the city. I want to try real mountain, but I have no known person who can go mountain with me. ^^;;

Well, to take photo with cycling is also interesting thing, when i ride. And to make write blog makes me fun. I write it in japanese on other server.

Usually, I use two cameras for taking photo. One is cheep digital camera. Using digital camera can take good quality of photo. And, I can use big size of storage. The cpu on camera is specialized for taking photo.  Another one is my mobile phone.  The quality of processor for taking photo is not so good on mobile phone. However, it is good for taking sun. When we use good quality camera, every light effect is computed by processor. It is good. But, when we use mobile phone then we can take sun with light line or cross. The mobile phone does not compute such light effect, so we can take an amazing interest photo.

Other reason of using mobile phone is data transfer. When we use digital camera, we need to take off the sd card from digital camera then put it into sd card slot on computer. Yes, some sd card can send photos through wifi. But it is expensive. On another hand, when we take photo with mobile phone and the mobile phone has dropbox then the mobile phone automatically syncing with doropbox. When we turn on our computer, the photos can downloaded to the computer automatically. And the photo is also uploaded to google+. Google+ has unlimited strage size for uploading photos. And we can easy share the photos to our friends, public domain and others. For taking the view for the city or nature when i ride mtb, I don't need zoom function. So, my xperia ray has enough resolution for taking such views.

Because of above reason, I uses two different camera when i take my MTB.

SNS : publishers - subscribers

Recently, many kind of SNS are released.

Some of japanese go out to SNS what provides the service for world wide as FB, Twitter and Google+.  Well, google provides two different SNS. One is Google+ and another one is Youtube. Youtube live is provided from google+ hangout.

The view from connectibility of users they are two different thing. Facebook can allow only bidirectional connection between users. You can follow some page with like button, but it is little bit difference. Twitter and google+ can allow the one way connection between users.  This difference comes from the view of publisher and subscribes , i think. On twitter and google+, publisher wants to describe something to others. But, the publisher don't want to care about who has interest in the published contents. If the user has interest in the contents then the user will subscribe the publisher. On the facebook, the publisher want to tell something to his friends. So, the main target of subscriber is publisher's friends. The subscriber checks the new post from his friends. On the google+, publisher can select the subscribers' group for each post. And, subscribers subscribe the publishers' posts. I think google+ can take the good points of facebook and twitter.


Well, I follow(subscribe) some famas people on SNS. Some of them are private and others are for business. When I follow some business account users, they refollow to me. I think this is natural behavior. Some of famas people who are famas in world wide and i haven't met with them, they just publish some information to the subscribers. I think it is also natural, because this is usual publisher/subscriber model. The interesting point is next case. When I follow some famas people who is japanese and famas in japan. I don't know why but some of such kind of people resubscribe me, even if i don't provide any information and we haven't met each other.  


In some community, the resubscribing works as social manner. I was surprised about this culture. Because, for me, i subscribe some people, because i have interest in the publisher's post(topics). 


I found new usage of SNS connections. ^^;;; Because, in my opinion, to publish some information and subscribe some topics should be separated. Even if the system separates the view, however some people follow the other standard from other network. ( I don't know this is good thing , not good thing or just culture gap )


I should go to bed ^^;;; I become to miss what i am writing on this post because of my current sleepy feeling ^^

Well..... where is a wasabi????

I drank little bit more......

Hummm........
I can not find the taste of wasabi......

Maybe...... 30 seconds later from drinking, I could feel small smell of wasabi.....
I think the ginger taste was too strong for wasabi smell..... ~_~;;;

SonyEricsson xperia ray ICS ver.

I reviewed little bit about sony ericsson Xperia ray, when I update from GB to ICS.

Well, from the beginning, one of the problem on my phone is the function of phone call. This is not only for ICS but also for GB. Because, for me, the largest application is address book. Usually, I use default address book app. When I start up the address book app, it is ok. First problem is scrolling. Sometime, the app gets a crash, when i try to scroll down my address book. And second one is when i try calling. When I call someone, I open address book then I choose one of elements in list. when the time, the state changing from address book to calling has more than 3 seconds. I don't know why it is happened. But, it is one of big problem for me.... because it is mobile phone...... ~_~;;;

I think next topic is related with above thing. The next topic is about memory (RAM.) I think(not sure, because i forget) the xperia ray has 512MB of ram.  The real usable size of ram is 340MB. It was enough big size for the first 2-3 month. However, there are many new app released every month. And, I installed 3-4 new app for each month. When the free ram size became less than 100MB, the response performance began to quite bad. Usually, I refreshed the memory and killed background processes. However, it was not enough for this 2-3 weeks. ( I think I need to change the priority policy for some of apps "I don't know it is possible or not, now")

My recommendation for choosing new android mobile phone ( if you have some coice and you don't know which one is better) is that you should choose the device what the ram size is as large as possible.

Well. my meaning is not xperia ray is bad. I like this mobile phone. It is so light and easy to use. The camera and screen quality is quite nice. (I don't use, but) the sound environment is also good. If you don't install too much applications then the  response speed is also good.  Now, i don't want to change my mobile phone ^^

I want to change my android tablet, because it is enough old for real usage..... But, before to get new tablet, I want to change my MTB, too. I use my current MTB for 8-9 years. So, many parts will have problems (or already had problem but i didn't fined it.) So, i am thinking that to get new one is also one way ^^;;;

Android :: speed

   Usually, our system becomes speed (performance) down, when we install many application. We can say same thing onto our android phone.

   Some of my friends also said same thing. In this post, I did not any evaluate about anything. All of my writing in this post is only from my experience and feeling.

  Many case, the performance down on android comes from RAM space. I used task manager for this problem 2years ago. And some people do it. Well, I found one thing. We can control the task execution because of the application. However, many of android task managers are executed as background process. Such kind of application will be one factor for speed down.  I removed such kind of background executed task manager.

  This is my result to use android mobile phone. The problem for speed down is application cache and background executed process.  So, I use two application.

  First application is app2sd. The main feature of app2sd is move application from phone strage to sd card. However, app2sd has another function. The function is cleaning cache. When we use android device for long time, then many application store many cache. So, app2sd can remove them.
 https://play.google.com/store/apps/details?id=com.a0soft.gphone.app2sd&hl=ja
Usually, I use above app.  (I think this is japanese version. But in english is also exist. I have used this app in english. However, current market show me only japanese version....) ** Be careful!!!! In the market, some app has same or similar apps. However, I have read that some of them works strange (attack) to your computer in some forum. You should check the app review before to use the app.

  Second, I use task killer named Simple Task Killer.  Task killer can categorize two class. One is only app and another one is executed as background process. When I started to use android phone, I used background executable task killer. However, background executable app also eats the ram space. And the app begin to bottle neck. So, I removed such kind of apps. However, usually, an android mobile phone will have many background processes and became to low speed. So, we need to kill some tasks. And, i started to use task killer without background execution.  My android tablet has preinstalled task manager, so i use it.
https://play.google.com/store/apps/details?id=jp.co.aplio.simpletaskkillerfree&feature=search_result#?t=W251bGwsMSwxLDEsImpwLmNvLmFwbGlvLnNpbXBsZXRhc2traWxsZXJmcmVlIl0.
(sorry, but my using app is in japanese....)

 Third, I use memory booster. Memory booster meaning is (maybe) garbage collector. Small ram is a big problem for android devices. So, I use MemoryBooster. This app can release the ram space and also can kill tasks. I don't know why but there are different set of tasks are shown. So, I use both of them.
https://play.google.com/store/apps/details?id=imoblife.memorybooster.lite&feature=search_result#?t=W251bGwsMSwyLDEsImltb2JsaWZlLm1lbW9yeWJvb3N0ZXIubGl0ZSJd

I wrote this blog 1-2 month ago. And I stopped to write half of this. My dashboard has many this kind of half written blogs ^^;;;;;

Don't update ubuntu from old version to 12.04LTS

As the title, I think you should not update from old version of Ubuntu to latest version of ubuntu.

Yes, if you customize so much and to re-customize is quite difficult then you can not avoid update.  However, if you do not customize so much then you should remove current installed ubuntu and cleaninstall the latest version. The reason is following.

From 08.04, I had many troubles for ubuntu update especially X configuration. I use 4 different ubuntu desktop and 2 virtual computer on vmware. Only on vmware's ubuntu can be update safely. My friend is also using ubuntu. However, his computer also had many troubles. He using some server software on ubuntu. So, he did want to update from zero. And his computer got crash before x started. He used some days for repair that problem. For me, many of computers are only for desktop except one computer. So, usually, I update them and got crash then I remove them and reinstall from zero. Because, I don't want to use time for repair the os. When I started to use ubuntu, i tried to repair my computer. However, it needed too much time.....

And, recently, ubuntu changed default desktop from GNOME to Unity. Like as Windows and mac os, unity is target to tablet pc, too. But, same as others OS, the UI for computer is quite bad. Using way for fingers and mouse is quite opposite(different?) way. So, to use unity with mouse is very difficult. And, from some versions ago, ubuntu stop to use xorg.conf. And, there are many different documents and many different way to solve the problem in the internet. If we will be able to follow one way then it may work. But, i cannot remember what did i do half years ago. And, the system became to unstable state....

Like as above, continuing to use ubuntu only with update is (sometime) difficult.


Actually, I try one computer to update from 11.10 to 12.04. It worked. But the behavior was not stable. So, I reinstall the OS also for that computer. Then the computer become to stable. My personal opinion, Ubuntu 12.04 is the most stable version in the history of ubuntu (except unity). So, to cleaninstall have a merit for you, too.

My dashboard

There are many pre-posts what I wrote bit but not completed in my dashboard ^^;;;

Ubuntu 12.04 LTS : review

I tried to use Ubuntu 12.04 from last week.

For the total view, I think 12.04 is the most stable version except default desktop. This meaning is that if you will clean-install from zero then the system is so stable.

I tried to update from 11.10 to 12.04. The updating was completed. But it was not stable especially x-windows system. Usually, I work on ubuntu and intelli-j. So, x-windows system's problem is critical for me ^^;;

Finally, I formated the system partition and reinstall 12.04 from zero. And, I changed window manager to GNOME, then the system became quite good. Before 11.10, my computer could not find sound board. ( my computer has one sound card, one onboard sound card, and one USB sound card) I think my computer could know the usual sound card when i installed 10.04(?). However, after some updating, the system could not find any sound card. So, I gave up to setting up and I bought new USB sound card. However, it was not worked on my computer, too.  However, when I installed 12.04, the machine made boot sound just after install it. It made my surprised.

I don't know the problem is from my graphic board or Ubuntu. But, it is difficult to play flv or mp4 file. (because, my video card is only PCI-Express x1).

For the multimedia machine, I consider to buy one small pc for playing them..... Windows? mint linux? or some others?

Xperia ray (ST18i) : GB ---> ICS

I use Xperia ray (ST18i).
Xperia ray has multiple type of versions.
I know JP version, US, North europa, Asia, and china.

And, I know JP version is one of the worst version for new release because of economic and political reason. So, I bought from hong kong. However, china version also had different meaning of political reason. I thought it is good for SIM free version. However, the bad point is that the phone cannot access to google account even if it is android phone. So, i decided to flash the rom from 2.3 to 4.0. I used official rom for north europa version. Many sites explain how to change rom. So, I don't do this. This time, I got friend's help. Because, the rom flashing too is provided for Windows or Linux. I have linux machines but it has many risks for flashing rom with linux machine.

I thought that I should wait for real release for my phone. The first release was last april for US version. And, I waited almost 1 month. However, it could not get new release. This meaning is that the version has more complex implementation than common release. This meaning is the version of ICS also cannot access to GooglePlay, google map with my account. youtube with my account, etc. So, I changed....

The largest change is setting up menue. For the GB users, I think ICS's interface of OS setting up is version down. It is more difficult to use there menue. However, most of android is not so difference. I can use many think as GB. The response quality is not so difference. I don't know why but I think the resolution for width is larger than before rom. The using way, I feel this version of rom is wider than before. On the before rom, my phone could not fined my mp3 files from my sd card.

Now, I can use google play, gmail, gtalk, youtube, map, navi and etc... This change was so big for my smartphone life.

The bad thing is camera function. The quality is almost same. But, the UI became worth than before.

And, I set up the AP. First time, I added AP information. And, it was working when the time. After that, I wanted change the MMS information. Then suddenly my phone  could not connect to 3G network. I didn't find this problem. Because, I uses wifi on may time in my house. When I went to biking, I found this problem.  The solution of this problem is simple. 1. you need to remove previous setting. 2. Create new AP setting up. And put correct infomation.

Review :: Google Drive

  The first day when the google drive was released I try to use google drive. Actually, I thought I will not use google drive any more. Because, it has only 5GB strage for free and the provided client package for OSX was not work. And it was also difficult to manage the files from web browser.  The initial state, my home space had many files and directories what I created on google doc, google note, and etc. Actually, I didn't want to see them on this strage.....~_~;;;
 
  Today, I try to install the google drive client for osx again. The client can be installed to my MacBookAir Lion. And, it works well. My personal opinion, the setting screen of sync policy has many spaces to improve. It is not so easy to understand. Finally, I removed all my data from my space. Because, I checked the select box what is only sync some folders to this computer. And, I sync them and I moved them into trash box ^^;;; Happily, I didn't need them. 

  Well, the client of google drive is almost same spec with Dropbox or SugerSync. I cannot fined some special point on client. The sync speed is also similar with both of them.  I didn't touch it with offline, so i don't know when i will touch them when my computer has no network communication. When this time, I thought I got only the new online strage.

  After upload some files, I try to access to google drive from web browser. After this timing, I could know the strong point of google drive. When I open some jpeg file from google drive, it is so wide and clear. Usually, the claim to network drive service is too small or so difficult to see the files data.

I added many files to catch.com. It is one of the cloud note service as Evernote. Evernote had big crient software but the response was so heavy. catch.com can be accessed from web browser or client software on mobile devices(Android, ios, etc). I added many files to it. Because, catch.com has no maximum file capacity. I can upload files 70MB/Month.  The good point of catch.com is maximum capacity. It is the most point. But, to check file on web browser, it is so small to do it..... 

But, google device does not have such problem.  I think I will use not only catch.com but also goodle drive. I need to make some using stile of there cloud services efficiently ^^

Smart phone app and disaster

 I already wrote about following in some place.
 And, I also wrote this in japanese first. Because, I wanted to know about this for japanese engineers.

 Many of u know the earth quake in japan, it was occurred one years ago. And, many of online services was developed or tested for such kind of disaster attacked.  Before the earth quake, I had claim weak buttery on smart phone. In the place where is attacked by disaster, it needs more than one weeks for recovering the infrastructure. However, current mobile phone especially mobile phone can be used only half day to 2 days. It is not enough in such situation. It is enough to call at least one know person. It is one opinion. However, in many case, it is also impossible to call one phone call to known person due to the network traffic jam.

On another hand, facebook tested a online service what we can tell our life through the facebook, when disaster will be happened. Well.... the last version of this service was needed to access to facebook. In the real place where is attacked by disaster, it is difficult to connect to facebook with 3G network. And this behavior will make bigger traffic to mobile phone network than phone calling.

I think it is enough to push only one button from smartphone app. This meaning is that facebook already separate messenger from facebook app. As this, facebook or someother web service provider can make independent application for there web services. And the button pushed will send minimum information to server using as sim id or phone number. My image is similar with "whatsapp". It is based on mobile phone number. But, the service should save the communication size. Yes, users must download the application before the disaster.

On another hand, the OS for mobile phone should be changed, too. I think mobile phone should have super power save mode. If i was in the power critical situation, I don't need to receive the phone call on demand. SMS, too. We just need to get there information as pull model. Current smart phones are attacking to mobile phone network with too much packets. In such critical situation, we don't want such a useful application. There application should be stopped in such situation. The scheduler in OS also need to changed for saving power.  I think this function is not used in usual situation. It will be needed in special situation. And, I think we should to keep mobile phone's turning on  as long as possible. If it is possible, then the service should accept from phone call from public phone. The earliest service was public phone.

Player/stage javalient3 (Sorry, this post has no new information)

Player/Stage, javaclient3 was released.
Actually, I didn't know about it untile this year.


You can get the javaclient from
                  http://java-player.sourceforge.net/


You can get the some sample code from
                  http://java-player.sourceforge.net/examples-3.php


It has many new elements. I will write a sample code and compile way, later.
I DL them from CVS. CVS version has no ant file. So, I need to import to IDE or to write ant file for compiling.


Kindle cloud reader

Today, my chrome app pool has new app. Actually, I think it is installed automatically.... I'm not sure but I have no memory to install the app. The app is provided by amazon. Name of the app is "Kindle cloud reader". I installed kindle app to my mac. However, by this installation, i could delete the kindle app from my mac. Actually, I will not be able to read any books on my mac, when I go out. However, when that time, I'll have my nexus one and tablet. Both of them have the kindle app.

Now, I try to buy some book with free cost. (it's very nice that i can get some kind of knowledge by free. But, I'm weak for english, so it is hard to read them for me.) And try to read it. Usually, I didn't use kindle app on my mac. because, I needed to boot special app for reading app. But, now, I don't need to boot any special app only needing is to push app on chrome. I read some pages. I'm reading "what is Node". I cannot explain about this book, yet. Because I just started to read.

The review of kindle cloud reader is following. This is so easy to read. I think this is because of resolution of my computer. But the character is so clear and the book part is so wide. So, wide space for books are quite nice. However, the height is not enough. I'm using MacBookAir13inc. When I use this mac for reading book, total number of lines for a page is so small.  I could read 20-25 lines for each page. Yes, it is enough easy to read. However, it is little bit difficult to read some technical books what I wanted to check body of sentence and some figure. I need to change pages more than paper based book.

And, the books are synchronized between tablet, smartphone and cloud reader. So, I can read it with out stable network, too. This is another good point for me.

In total elements, I like this tool. And I will use it in my house, in my desk, in cafe, and some other place where I wants to use.

Japan is too late for book market. I think one of big reason is economical thing. However, If the authors and printers consider more for business model, e-book has good market power. They should change mind more.

My style using cloud storages

My main working machine is Mac OSX snow leopard. I'm using also android mobile phone, android tablet and linux desktops. The big problem for using claude strage is supports for platform, public policy and size of strage.

Dropbox is one of the famous claud strage. The lient software for Dropbox has good functionality, even if it is free uses. However, Dropbox is weak for strage size. Yes, Dropbox has more than enough functionalities. And we can use dropbox for free. If you want to use larger strage size then you can pay. The size for free users can use 2GB. And you can pay for 50GB or 100GB. The amount of cost is not so big. But, it can make dammages for students life, even if it is small amount of costs. 

On another hand, Box.net, N-Drive, SkyDrive and UbuntuDisk (I'm not sure the correct name?) are also good strage services what we can use for free, too. 

My private opinion, Box.net is also good cloud service. Box.net can use 50GB for free. And Box.net has good web interface. However, the client for Box.net on mac osx is not good. Before version 3.0.1, the client didn't work on OSX (snowleopard). Now, it works on OSX. However, the client's UI is not user friendly. It is difficult to use. And for the synchronization between cloud strage and local strage, we need to pay every year as dropbox. I can say both of Box.net and Dropbox are good service and it is enough cheep cost for using there good services, if i'm working.... ^^;

SkyDrive is provided by microsoft. Users can use same account with hotmail. It is one of the good thing. But, my private opinion, same as Picasa by google, I don't want to upload my private and important data to there. Because, I'm not sure about the publication policy. I makes many mistake. If i will make mistake to setup the publication policy for my private documents..... However, they are good for uploading the photos. Especially , SkyDrive can be used 25GB of storage. it is more than good for web photo storage. And Google services can be used 1GB for pictures and 1GB another storage for documents. And, SkyDrive may not have client application for MacOSX.

N-Drive can access using WebDAV. For the accessing to use WebDAV, N-Drive is more stable than Box.net (this is before to be released ver. 3.0.2(box.net). we needed to access with webdav)  
* actually, I didn't know about this. But, in the internet, there are two different N-Drive with similar service. My meaning is the service provided by NAVER. 
This is good for android tablet, too.

Ubuntu one is similar service with Dropbox. We can sync data between cloud and local directory. But, it has weak for platform. They support only for Ubuntu, Android, iOS, and Windows. They don't support to OSX..... With out this point, UbuntuOne is also one of the good choice to use cloud data management.

Like as this, even if we have many cloud account on the ineternet. however, to use them with samething is difficult. ZeroPC can solve it. ZeroPC looks like online OS. The service can transfer the data from one cloud to other cloud. Current version is 2.0. The support cloud is following. 
Box.net, Dropbox, Evernote, Facebook, Flickr, Google Docs, Instagram, Picasa and SugarSync
Now, it is not support for UbuntuOne and N-Drive. However, For free account. ZeroPC also have limitation for data transfer. We can transfer 1GB/ month.  However, if we use Dropbox for sync with local and claud and to use ZeroPC as bridge then we have some other big claud strage. It is not the most convenient way  and sometime we feel lazy about this way.  We need to consider something about them. But, it is one way to use multiple claud on many devices.

USB server

I went to working trip at last weekend. In that trip, I could buy an USB server.
USB server is like as converter from USB HDD to NAS. We just need to plug power cable, LAN cable and USB cable. And after small setting up, it will work as NAS (Network attached strage).

Following URL is the USB server what I bought. (in japanese) 3,000 jpy
http://www.planex.co.jp/product/usb/mzk-usbsv/

I try to use this usb server in my house. I had some point where I though little bit for setting up.
client environment:
MacOSX (Snow leopard)
Ubuntu 11.10

The default network setting up is 192.168.1.245
Some of network uses different network address, so you need to change ip for your computer as fixed address. Then you can access this server from Firefox or chrome.
The server ask the login user name and password for setting up. You dont need to connect direct between your computer and usb-server. You just need to plug to netwrok hub for both of them.

First you need to change the IP address to fix to your LAN environment. If you will use DHCP client, then you need to use an application what is added in CD-ROM. the application can find your USB server on your netwrok by automatically. Then you will be able to know the new address for USB server. The application is in the for OSX directory, You can copy to your mac or linux machine. It is jar file (I forgot the exact name, because I already change the name of jar file....) Yes. it is jar file. you can execute it on any machine if it has java environment. Then you can reaccess to the server.

I turned off the FTP service for security, And I turned on samba access. And I made my private user for accessing samba service.

When you change settings, be careful for saving button, It is too difficult to understand the button for saving due to the interface design problem, if i can understand japanese. I tried more than three time on some of step because I pushed some other save button...... I hate this kind of complex ui......


Well, I tried to use it.
From OSX, the work is fine. I can use it as usual nas. And the transfer speed is base 100. So, it is good.
When I access to ubuntu (classic gnome environment) had bit problem. When I access to this server, the work is fine. And I transefer some small files it fine, too. But, when I sent some complex data structure, the system load becomes to high and stop.......I think it is default file manager or my setting problem. I need to consider more for /etc/fstab

Strange SSID

Yesterday, I backed from working trip. To my house from rail line and bus top, I need to walk for 20 - 30 minuts. In this season, it has strong snow storm. And the road for walker has too much snow as 20- 30 cm. It is too difficult to walk such a distance with laptop and some many things. So, I was picked up by my friend by his car.
After taking dinner, we went to a cafe. And we worked 30-60 minutes with coffee. He said "Oh, here we can use WiFi in this cafe! Because I saw a seal what we can use WiFi here." So, we tried to use WiFi. (we cannot use any network in that. I don't know why....) When that time, I was surprised because of name of SSID. I forget exact name but it was following.
"password"=queryForfreeSPOT(ASM)
Actually, in the cafe, it has another SSID named freeSPOT. First I tried normal "freeSPOT". But it did not work. And he said that the seal said password is password. However, i have no idea that the strange SSID is correct or not. Because in the cafe, I could find some other strange name like as some default name as (001D3FNDSJI)
001D3FNDSJI
001D3FNDSJI-1
001D3FNDSJI-2

I was considering something..... At that time, he tried that strange SSID. It could be accessable with that password "password". So, i also tried it, too.
It was also strange network. I cannot access to any site. But the DSN setting was correct. So, I can send ping to my uni. with no response. But I got correct ip address. First time to see this ssid, I thought it is fake or malicious network........

There are many WiFi services and different membership model. So, I don't follow any service of access point. So, I don't know that such kind of SSID is common or not.... but it was strange for me...........

Ubuntu 11.10 :: GNOME

After Ubuntu 11.04, default window manager was changed from gnome to Unity.
In my opinion, Unity is good for using on tablet pc. However, it is difficult to use on desktop or laptop pc.

If you don't want to use Unity desktop as me, then you can use GNOME classic. On default, GNOME classic is not installed. You need to install from command line or package manager. The name of package is "gnome-session-fallback". (I haven't meet the bug, but some bugs are discussed in the Ubuntu forum.) Then, you can choose GNOME classic when you log on. I tried some window mangers, however no window manager is better to use than GNOME classic for me. GNOME classic has two mode named GNOME classic and GNOME classic no effect. With my desktop pc, I could not find any difference. (because i don't use any visual effect ^^;;;)

Well, for customizing the gnome panel, we just needed to dag and drop to the panel for adding some icon to start some application. Or we could use with right click. However, we can not find managing options on the GNOME classic panel even if we try to right click on the panel. One day, I missed to put an icon to the panel. And the icon was as obstacle for my work.
The solution of managing the panel on GNOME classic needs to use "Alt + right click" For finding this thing, I used more than one week.....

Android + Softbank mobile :: SMS and MMS

I'm using Nexus one.
I think you already know about nexus one. Nexus one is one of the android mobile phone developed by Google and HTC. It is not possible to buy nexus one in japan.

I already wrote about japanese 3G signal. Japan has 3 big different phone company. NTT DoCoMo, Softbank mobile (vodaphone), and AU KDDI. DoCoMo and Softbank mobile are using W-CDMA and AU is using CDMA-2000. Many people think that W-CDMA is similar with CDMA-2000. But, it is extension on the GSM. The W-CDMA is little bit different from GSM especially for MMS. The specification of MMS on W-CDMA had little bit different bit from GSM. Android phone cannot access to MMS server by default. So, we needed to compile the android kernel for receiving the MMS on Softbank mobile. Actually, I didn't re-compile the kernel on my phone. Because, it is mobile phone. To re-compiling the kernel for mobile phone has many risks for security and my economy. By such reason, I didn't use MMS on my phone.

2-3 weeks ago, one of my friends who is also using android phone told me that the android market has a application that makes possible to receive not only SMS but also MMS without recompiling the android kernel. It was amazing thing for me. Because, I thought it is impossible to receive the MMS without recompiling the kernel on the W-CDMA. However, I got second time amazing after knowing the mechanism. Softbank mobile made this application independent from the OS. This meaning is that the application has all modules for receiving SMS and MMS, even if the OS has such modules and functionality. It is only my opinion but it is not elegant way to develop the software.

Pocket WiFi + Nexus One

Last a month, I used PocketWiFi with B-Mobile SIM + Google Nexus One with Softbank mobile SIM.

I used this combination for a month because the softbank mobile had problem for 3G data communication due to the wrong parameter written by staff. The communication speed was too slow. So, I try to use B-Mobile for data communication. I wanted to use b-mobile but I didn't want to change the phone plan from softbank. Then, I try to use Pocket WiFi.

The largest merit of using PocketWiFi is that we can use 3G network at most 6 devices at a same time. When we are starbacks, some coffee stand, or some other places we can use 3G network through the wifi.

The speed was enough for web browser. However, for the data communicating through the android application, some of them didn't work. And, the buttery power also had problem. I need to charge the buttery every 1-2 days, even if i didn't use it. And, I had some situation that I wanted to use it however I forgot to bring it with me or to charge it. If it was in the winter, we have many pocket on our wear. However, in the summer, it is difficult to find the space for bringing it.

From the begging, PocketWiFi was designed for using Laptop PC or portable game player. And we can use it also on the mobile phone. However, to use pocketwifi with mobile phone was not convenient.

I already return to use only nexus one.

The difference of price between softbank mobile and b-mobile. The price by b-mobile is little bit cheaper than softbank. But, it has limitation for data communicating speed. But, it was useless for mobile phone.......

Pocket wifi

From today, I try to use pocket wifi. This post is first review for using pocket wifi. Why did i start to use pocket wifi? Usually, i use many devices that have wireless LAN. Ex, nexus one, android tablet, mac laptop, Linux netbook,etc,etc.... i only can use nexus one, when i go out from my room or university. Nexus one is good device for mobile phone. However, it is not enough screen size for working. So, i wanted to use my tablet in outdoor,too. On such timing, softbank mobile 3g network becomes to unstable state. By such situation, i decided to try the pocket wifi with b-mobile network. Because i don't want to change my phone number by this thing. Well, b-mobile is one of the mobile phone service provider using docomo's 3G networks. I bought sim card with a month contract. The good thing is that we can use at most 6devices at same time. Wherever we can use network. But, the buttery life is not so long. Maybe three hours. And, i'm not sure but i think it is slower than softbank mobile. The setting up for initial use was not easy.

App Backup & Reinstall - Android マーケット

Android Application

Usually, android applications are installed to strage on the android device.
However, the android device has limitation for strage.
So, installed to strage is not happy for user.
This application can be moved android application to SD card.

My Nexus one has limitation for application install area.
And, it is too small for installing many applications.
It is very nice application.

But, it is not possible to move all application to SD card.
This application automatically detect that what application can be moved and make the list.
The possibility is based on a variable that to where can we install it.
So, if you have android shell then you can change the variable for some application.
You will be able to find the way to change the variable by the google search.

Nexus One :: Time synchronization through the network

Clock synchronization
The two-three weeks after earthquake, my nexus one lose more than 10 minutes. Many clocks on my devices what are synchronized through the network are correct time. And, archos 101 also ticked correct time. However, I thought it was due to the earthquake attacked to the tower for radio signal of time sync.&nbsp;
However, it was not only in Japan.
http://www.google.com/support/forum/p/Google%20Mobile/thread?tid=0541d85a152acd13&amp;hl=en

Now, my nexus one is ticking almost correct time ^^
It might be by the Android 2.3.3. What happend at that time? @_@?

Japan :: mobile phone

  In Japan, it's used w-cdma protocol for mobile phone. W-cdma may be used at only  Japan and Korea. Many peaple make image as cdma2000, when you read "cdma". Because, GSM is used for mobile phone as standard protocole in many country. And some countries are using also cdma2000. Between GSM and cdma2000 are not compatible. However, between w-cdma and GSM are compatible. Cdma2000 is also used in Japan. )

  Well, i had small trouble about this cdma, when i told about Japanese mobile phone protocole with a professor who came from overseas.  He asked me about my carrier on my phone. My phone is softbank mobile. And softbank mobile is using w-cdma protocol. You already know that w-cdma is not widely used protocol. And if you say cdma then it points to cdma2000. He also thought so. And, it made small discussion about that cdma is compatible or not. Actually, i could not explain aboutit well.

  I remind about it. And i want to check that how my nexus one know about signal. Then nexus one said that softbank is used. However, it is using GSM. Sure, it didn't seal in Japan. So, it is natural that it don't show as w-cdma.

Now, the protocol is moving to 3.5G or 4G.

SSID in japanese?

Usually, we don't use japanese for setting to computer. Because, japaese needs at least two byte. Usually, many computer systems are designed for one byte. So, to use japanese in the system setting was not common way. If he is usual engineer then he will not set japanese for the setting to SSID. I was not do such a thing.

Today, i read a tweet written by my friend. He wrote that he could see the japanese ssid from his house. I was really  suprized when i read it. So, I asked prof. Google about this ssid expression in japanese. So, it is  exist.

Now, I had no wireless devces for trying it. But,it is so intersting thing for me.
